Series SF2 Sight Flow Transmitter
Brand: Dwyer Instruments, LLC
The Series SF2 Sight Flow Transmitters combine visual confirmation of flow with a relay or pulse output.
The SF2-1 offers a SPDT relay output and the SF2-2 offers a pulse output proportional to the rate of flow. The 4.5 to 24 Vdc pulse output is compatible with most digital logic families.
Features- Brass, solid body construction, one piece composite rotor, and ceramic shaft delivers durability with broader chemical, temperature, and pressure capabilities
- Set points are fully adjustable over the specified flow range
- The dynamic operation of the rotor guards against jamming and false actuation
